Other

• Phase 9: UNIQUE constraints on WITHOUT ROWID tables — the implied
  sqlite_autoindex (keyed by the unique cols + PK cols, numbered by SQLite's
  declaration-position rule) is written and maintained, and the constraint is
  enforced; verified by sqlite3 integrity_check
• Phase 9: real VACUUM compaction — rebuilds the database into a fresh, gap-free
  image (no free pages, defragmented b-trees), shrinking the file while
  preserving rows, indexes, triggers, and user_version; the result passes real
  sqlite3 integrity_check
• Fix: b-tree cursors now skip empty leaf/interior pages left behind by heavy
  deletes (previously a scan after deleting most rows errored with "cell index
  out of range")
• Phase 9: WAL write path — PRAGMA journal_mode=WAL switches the database
  to write-ahead logging; commits append page frames (with SQLite's exact
  checksums/salts) to the -wal file, PRAGMA wal_checkpoint writes them back
  to the main file, and reopening loads an uncheckpointed -wal. Real sqlite3
  reads graphitesql-written WAL databases (checkpointed or not) with
  integrity_check = ok
• Phase 9: secondary indexes on WITHOUT ROWID tables — CREATE INDEX on a
  WITHOUT ROWID table builds and maintains a b-tree keyed by (indexed cols, PK
  cols), as SQLite does; verified by sqlite3 integrity_check
• Phase 9: INSTEAD OF triggers — INSERT/UPDATE/DELETE on a view fire its
  INSTEAD OF triggers (with OLD/NEW), making views writable; without one,
  modifying a view is rejected as in SQLite
• Phase 9: WITHOUT ROWID tables — stored as a PK-clustered index b-tree
  (records held PK-first), with CRUD, composite primary keys, and
  INSERT OR REPLACE. graphitesql-written WITHOUT ROWID databases pass real
  sqlite3 integrity_check, and graphitesql reads sqlite-written ones
• Phase 9: automatic indexes for UNIQUE / non-rowid PRIMARY KEY — graphitesql
  now writes the implicit sqlite_autoindex_<table>_<n> b-trees and maintains
  them across INSERT/UPDATE/DELETE. Fixes a file-format bug where real SQLite
  rejected such databases ("wrong # of entries in index sqlite_autoindex_*")
• Phase 9: PRAGMA recursive_triggers — triggers may fire other triggers when
  enabled (bounded to 1000 levels); off by default, matching SQLite
• Phase 9: broaden the differential corpus to 1658 queries (window functions,
  derived tables, correlated subqueries/EXISTS, real-valued expressions) and
  render reals through the %.15g-compatible formatter
• Phase 9: explicit window frame clauses — ROWS/RANGE/GROUPS BETWEEN … AND …
  (and the bare-start form), with UNBOUNDED/CURRENT ROW/N PRECEDING/
  N FOLLOWING bounds and an accepted-and-ignored EXCLUDE clause
• Phase 9: derived tables — FROM (SELECT …) [AS] alias as a sole source or a
  join operand
• Phase 9: views (and CTEs) usable as a join source — a view or CTE may now
  appear on either side of a JOIN, not just as the sole FROM source
• Phase 9: row triggers — CREATE TRIGGER … [BEFORE|AFTER] {INSERT|UPDATE|DELETE} ON t [WHEN …] BEGIN … END with OLD/NEW row references and DROP TRIGGER;
  fired non-recursively (matching recursive_triggers = OFF)
• Phase 9: foreign-key enforcement behind PRAGMA foreign_keys = ON (off by
  default, as in SQLite) — child-side parent-existence checks on INSERT/UPDATE,
  and referential actions on the parent (NO ACTION/RESTRICT, CASCADE, SET NULL,
  SET DEFAULT) for DELETE and UPDATE; FK clauses are now modeled in the AST
• Phase 9: window functions — row_number, rank, dense_rank, ntile,
  lag/lead, first_value/last_value/nth_value, and aggregate windows
  (sum/avg/count/min/max/total/group_concat) over
  PARTITION BY/ORDER BY with SQLite's default frame; verified against sqlite3
• Phase 9: real-number text formatting now matches SQLite's %!.15g exactly
  (15 significant digits, scientific past the [-4, 15) exponent window)
• Phase 9: correlated subqueries (scalar (SELECT …), IN (SELECT …)) and
  [NOT] EXISTS (SELECT …) — the subquery resolves columns from the enclosing
  query's current row via an outer-scope frame stack
• Phase 9: recursive WITH RECURSIVE CTEs (anchor + fixed-point recursive term,
  UNION/UNION ALL), CTEs that reference earlier CTEs, and CTEs usable as a
  join source — backed by a materialized CTE environment
• Phase 9: EXPLAIN QUERY PLAN (SCAN/SEARCH plan rows in SQLite's format) and a
  rowid (INTEGER PRIMARY KEY) equality fast-path that seeks the table b-tree
  directly instead of scanning
• Phase 9: date/time functions (date, time, datetime, julianday,
  unixepoch, strftime) and printf/format — a dependency-free port of
  SQLite's date.c Julian-day core, verified differentially against sqlite3
